Move non repeating numbers from 2 arrays in new array

I want the numbers in the first array that do not repeat with the numbers in the second array to go to the third array

This is what I have done till now and it doesn`t work...please help

for(int i = 0; i < isir.length; i++) 
{
    for(int j = 0 ; j < isir2.length; j++) 
    {
        if(isir[i] != isir[j]) 
        {
            for(int k = 0; k < sirdif1.length; k++) 
            {
                sirdif1[k] = isir[i];
            }
        }
    }
}

I am entering the numbers from console with Scanner function...
